A　micro-solid-phase　extraction　device　was　developed　using　the　sol-gel　method　by　assembling　with　a　metal-organic　frameworks　(MOFs)　with　the　gel　to　form　a　1　mm　membrane.　Subsequently,　this　device　was　applied　for　determination　of　seven　polybrominated　diphenyl　ethers　(PBDEs)　in　the　water　by　coupling　with　the　gas　chromatography-electron　capture　detector.　Variables　affecting　the　extraction　efficiency　including　the　amount　of　the　MOFs,　extraction　temperature,　extraction　time　and　desorption　time　were　detected.　Under　the　optimized　conditions　(MOF　4　mg,　extraction　temperature　70°C,　extraction　time　50　min,　and　desorption　time　15　min)　recoveries　of　the　seven　PBDEs　were　in　the　range　of　74.9%　to　98.1%,　and　the　relative　standard　deviations　were　between　3.3%　and　5.7%.　Limits　of　detection　were　less　than　4.7　ng/L　for　all　seven　PBDEs.
